I am just finishing a similar repair to a 1/8 size bass. It came to me with the fingerboard off, thankfully. I aligned and glued the neck back on. Next, drilled with a quality 1/2 inch brad point bit that I tested to make sure it fit my oak dowel. Applied glue to the dowel and drove it in. Then added another 1/2 inch dowel at a different angle, same process. Fingerboard is now glued on and I'm putting the machines, strings, tailpiece, endpin and bridge back on. I used hide glue throughout the entire process. I believe in it, it worked well for hundreds of years before the advent of modern glues. I like the idea of a peg and reamer going through the fingerboard like that, but isn't the visible portion of the peg end grain, against the face grain of the fingerboard? It looks nearly invisible, but how will it look as the woods start to expand and contract differently due to their opposing orientation? I did a through the fingerboard repair pinning, exactly as described above, about a month ago. Left my dowels 5 mm under the surface of the fingerboard, then made two face grain ebony plugs to fit over the dowels. Covered the visible circle outlines with ebony dust and added thin super glue, worked it flat with scraper and steel wool. Virtually invisible, unless you look very carefully. My concern is that my plugs came from a different piece of ebony..... how will it look after the wood starts moving with seasonal changes.......we'll see.

I have removed quite some guitar fingerboards. When you heat it up with an iron, the kind you normally use to iron your cloths, you can wiggle your knife in between the neck and fingerboard. At about 65 degrees the glue lets go. This works for sythetic glue as well as hide glue.

@@maestrokimon I could not find the email. I teach in the Philadelphia School District which has an extensive and highly recognized instrumental music program. I've seen music change kids' lives just as El Sistema did for a generation of youth in Argentina. On a small, old factory cello, I glued, clamped, and put two long screws through the neck and into the block. Before I fill the top of the sunken screws and touch up the varnish, with a cheap furniture repair kit, do you think it will hold? The block seems secure and I don't have the skills to make a new one. Just hoping to get the instrument in a child's hands shortly!

Hello, I know a way to remove this kind of fingerboards glued with white glue, it's a little bit agressive method but it can save you sometimes. I start adding water with a syringe between the fingerboard and the neck and then I apply heat with a clothes iron, using a wet cloth between the fingerboard and the iron. The fingerboard will heat up and the glue will start to melt down. Then I start opening the joint with a sharp plaster spatula. At the beginning the progress is very slow but then it's easier. Water, heat, pressure and repeat. When the fingerboard is removed I press it on a flat surface, it tends to bend. The disadvantage of this method it's that it's slow and you may need to rectify the neck and the fingerboard. I hope it helps you, thanks for your videos!

Thanks for the share! I would have peeled off the rest of the handle that is still attached to the mortice. Glued the handle and made the drill from the opposite side of the fingerboard. From that place I would have put the peg (not through the fingerboard), then reattach the handle. Another way (may be better) to do it would have been to place some splines perpendicular to the crack to reinforce it. I would never drill the fingerboard.

As the neck is was also glued with white glue, it would be very hard/impossible to open the joint between the rest of the handle and the back. Same probleme there. Also considering the value of the instrument, this was the best solution.

How do I know that the hide glue had the correct conistency for a certain gluing job, meaning its not too runny or too thick? Is it also acceptable to oil or even dye the pegs aswell as the fingerboard. I dyed the boxwood endpin with black dye, swiped it off and oiled it with lindseed oil and I was happy with the rosewood like result, but Im not sure if its a bit sacrilegious or widely used process.

It is hard to say how to know that the glue is correct. Mostly I feel it with my fingers. I don't want a layer to form but it has to get pretty fast a bit sticky. Do some tests. I also dye the fingerboard some times. Also have dyed boxwood pegs for a client. No problem with that for me!!!

What you did seems appropriate for what is likely a cheaper student instrument. I had the same thought about heat. Even 40C (varnish safe?) will affect the PVA and make it susceptible to 'creep'. Perhaps experiment on scrap - wedge a blade into a small crack then heat in an oven to see if it will pop open. Thickness is no obstacle if you allow enough time. One warning - domestic ovens, even the most expensive, can occasionally 'stick' with the element on and go way over temperature. A fool proof way to limit the temperature is required! Maybe a hairdryer and a wide cardboard tube? So very impressed at the way you made the ebony end grain match the fingerboard.

Some constructive criticism: The time to remove the fingerboard was when the neck was off the body, the synthetic wood glue should have been applied to the break only and hide glue to the part of the neck that adheres to the block, and the hole for the reinforcement dowel should have been made without damage the fingerboard (because, as aforementioned, the fingerboard should have been off). A repair as seen in the video, makes it extremely difficult for the next repair, especially if it not known that there is a dowel through the fingerboard. Were the cello to fall again, a repair as seen above, will almost certainly result in severe damage to the cello because the fingerboard will not be able to release from the body, or the neck from the block. Any instrument that is worthy of a repair, even a child's instrument, should be done in a manner that respects the owner, considers the instrument's longevity and one's legacy, and also, the ease with which a future luthier will be able to work on the instrument.

I would have used steam and heat to remove the fingerboard.

Many have made this sugestion, but the steam ruins the varnish and the fingerboard is too thick so it wouldn't reach the glue.

But then I will have holes in my fingerboard. This is a cello not a guitar, much thicker fingerboard.

@@maestrokimon same principal applies,two very small holes to plug vs one large. Just trying to offer a different solution. Seems to me removal of the neck to effect a proper repair would be preferred.

@@maestrokimon I'm not sure what you did, but it should work with little to no harm to the finish. The process I use is very similar to the way guitar luthiers separate guitar parts for repair. Most guitars and cheap wood instruments are glued with PVA (polyvinyl-acetate) which is often yellow or white. If it has no effect on the glue bond, then it's either not PVA or the procedure is incorrect. The working principle is simple. The enemies of glue are solvents and heat. PVA is an acetate so water and vinegar will dissolve it. By applying heat and a solvent, you can slowly compromise the bond. I look for the largest separation at the glue I can find. Using a syringe with a fine needle, I squirt hot vinegar into the separation to get it started. I wait a few minutes and repeat the process sticking the syringe deeper and orienting the workpiece so the vinegar flows over the entire glue line. Do not allow the vinegar to dry out or the glue will bond again. You can help the process out by using a heating pad around the working area to help soften the glue. The goal is to saturate the area with enough solvent where you can progressively insert a spatula into the glue line to help separate it, working it across the entire glue line. The process take a long time, but eventually the glue line should separate easily. This process goes much faster using steam. I made a steamer from a cheap expresso maker, a hose, and a syringe needle. Connect the hose to the foamer nozzle of the expresso machine and the other hose of the tube to a syringe needle. You can also attach a hose from a bicycle pump with a needle used for filling soccer balls. After the water starts to boil, you should see steam shooting out of the needle. While you're separating the glue line, insert the steam into the glue line and allow it to saturate the glue line with hot wet steam. Every once in a while, try to work your spatula into it and squeeze in more vinegar. Here's some videos showing this process. The only difference is that they don't use vinegar: kzbin.info/www/bejne/kITFZoenn9NpqtU kzbin.info/www/bejne/oKHaYqybn5WXd7s kzbin.info/www/bejne/pYfaZGZrnpljeMU
